Skaeo EduSense
Campus Attendance & Presence Platform
A campus attendance and presence platform built for a client, now live on university campuses in India — not another ERP, but a layer that sits over an institution and keeps it accountable. Bluetooth beacons record attendance as students walk in, a mid-class code confirms they are in the room, and a live command center unifies attendance, academics, safety, and leadership decisions for multiple institutions on one multi-tenant platform.
Replaces the Roll Call
Bluetooth beacons in each classroom are detected by students' phones, so attendance is recorded as students walk in — no roll call, no app-tapping
In-Room Code Check
Partway through a class, faculty push a short code that can only be answered from inside the room — a real check against proxy attendance
Live Command Center
Live intelligence from 'who's in this room now' to drop-out risk, so mentors and leadership can intervene before it's too late
Multi-Tenant SaaS
Live on university campuses in India on one platform — a new institution is added without a new build
DPDPA-Compliant by Design
Built for India's 2023 data protection law, with a full audit trail on every consent toggle and privacy-first 1:1 face match
9 Apps & Portals
Two web portals and seven Flutter apps for students, faculty, parents, staff, security, and the Vice-Chancellor — Hindi-first and 10 Indian languages where it matters
